5-1: VXR-1000 Deviation Setting
On the connected mobile transceiver, re-
ceive a signal from an external signal source
with 1 kHz modulation frequency and de-
viation level of ±3.0 kHz (±1.5 kHz for the
"Narrow" mode).
This signal, when passed from the connect-
ed mobile transceiver to the VXR-1000,
should produced a transmitted signal from
the VXR-1000 with 1 kHz deviation at not
less than ±3.0 kHz (±1.5 kHz for the "Nar-
row" mode).
If the deviation level from the VXR-1000 is
not correct, adjust VR1002 (inside the VXR-

5-2: VXR-1000 Receiver Output Level Setting
When the VXR-1000 receives a signal from
an external signal source (on the uplink fre-
quency used by the portable transceiver)
modulated at 1 kHz at a level of ±3.0 kHz
(±1.5 kHz in the "Narrow" mode"), the out-
put passed to the connected mobile trans-
ceiver should produce a transmitted output
signal from the mobile at a level of ±3.0 kHz
(±1.5 kHz in the "Narrow" mode").
If the output level to the mobile does not
produce correct deviation from the mobile,
adjust VR1007 (inside the VXR-1000) so that
the transmitted output from the mobile is
modulated at a level of ±3.0 kHz (±1.5 kHz
in the "Narrow" mode").
6. Trunking System configuration
All trunking parameters depend on the con-
figuration of the individual trunking system
in which the connected mobile transceiver
is used. Please consult the CE22 program-
ming instructions, and the separate "VX-
1000R Trunking Interface Manual," for in-
formation about the software and other set-
tings for the VXR-1000 when integrated into
a trunking environment.
7. Miscellaneous
In order to improve the audio muting per-
formance of the VX-3000, a minor circuit
change was adopted from Production Lot
#03 (VX-3000L/U) and 04 (VX-3000V), and
this change was reflected in CE-19 software
version 1.16. This change affects the connec-
tion point for the Squelch (Mobile COR De-
tect) line, and the connection point is iden-
tified as "AF M
UTE
tation for the VX-3000.
The configuration version can be identified
by looking for the presence of a jumper con-
nection at jumper pad JP1002 in the VX-
3000U, or JP1016 in the VX-3000L. The con-
nections for the Mobile COR Detect line
should be made as follows:
